Comment on Can this be charged
wiegell@feddit.dk 3 weeks agoThank you for the elaborate response. Does this seem reasonable: Charging voltage 5 * 3,3v = 16,5v, charging current limit 100mA? And then put the whole thing in the garden? Would you take breaks?

I’d go even lower, maybe 50mA. The main issue you’re fighting is internal resistance, which will cause things to heat up. Your other issue is that I’ve averaged things, however it’s quite likely that one or more cells has a significantly lower voltage than others (and therefore a higher resistance) so can cause more risk.
If you’re able to get the pack apart and measure the cells separately that will help a lot

If you can get the pack apart, I’d just rebuild it. Replacement cells are as little as $2 each.
